One of the main features of the contemporary environmental crisis is that no one has a clear idea of what is going on. The author uses an extension of Marx's theory of alienation to explain why people find it so difficult to relate their different knowledges of the natural and social world. He argues that nevertheless it is possible to relate these to the abstractions of ecological discourse. Emancipation can come only through embracing science and rationality rather than rejecting them and, in the process, humanity as well as the non-human world will benefit.
